As you can see in those pictures, a Cinnamon has different colors, but what always stands out to me on Cinnamons are the alien heads. On the normal, there are 2 eyes in most alien heads, while on the Cinnamon, there is usually 1 large eye in each alien head, similar to a Mojave. Often with Cinnamons, the alien heads get "smeared" together, especially towards the tail.
